Have you considered using salad dressing instead of mayo? I too like a dab of sweet relish in my tuna, but sometimes I go for a squeeze of fat-free creamy ranch dressing, which is maybe 20-40 calories depending on who makes it. I've also used fat-free sour cream and tossed in some chives for good measure. A little spritz of balsamic vinegar is also quite the bomb. Congratulations on your will power. I always think of something Oprah said years ago on her show, she said something to the effect that we make and keep promises to other people all the time, but all too often break promises we make to ourselves. So today you kept your own promise to yourself, you go girl.
